The non-contact eye tracking is a nonintrusive human-computer interface providing hands-free communications for people with severe disabilities. Recently. it is expected to do an important role in non-contact systems due to the recent coronavirus COVID-19, etc. This paper proposes a novel approach for an eye mouse using an eye tracking method based on a context-aware based AdaBoost multi-region classifier and ASSL algorithm. The conventional AdaBoost algorithm, however, cannot provide sufficiently reliable performance in face tracking for eye cursor pointing estimation, because it cannot take advantage of the spatial context relations among facial features. Therefore, we propose the eye-region context based AdaBoost multiple classifier for the efficient non-contact gaze tracking and mouse implementation. The proposed method detects, tracks, and aggregates various eye features to evaluate the gaze and adjusts active and semi-supervised learning based on the on-screen cursor. The proposed system has been successfully employed in eye location, and it can also be used to detect and track eye features. This system controls the computer cursor along the user's gaze and it was postprocessing by applying Gaussian modeling to prevent shaking during the real-time tracking using Kalman filter. In this system, target objects were randomly generated and the eye tracking performance was analyzed according to the Fits law in real time. It is expected that the utilization of non-contact interfaces.

In this paper, we propose a Windows-based presentation system using laser pointer mouse. Major-characteristics of this system is to synchronize the laser pointing position with the PC cursor such that the laser can function as not only pointer, but also a PC mouse. It is shown that we use a special pattern to coincide the coordinate of the camera capture image with that of the pc window. We finally show its feasibility by some experiments with the implemented system.

본 논문에서 마우스 대신에 음성으로 명령을 입력하여 퍼지 추론을 통해 윈도우 화면상의 커서를 이동시키는 인터페이스를 구현하였다. 입력된 음성이 대체로 짧은 언어이기에 이를 인식하기 위하여 고립단어 인식에 강한 DTW방식을 사용하였다. DTW방식의 단점중인 하나가 음성길이가 비슷한 명령을 입력하였을 때 표준패턴 중 오차 값이 가장 작은 패턴으로 인식하는 것이다. 예를들면 아주 많이 이동해 라는 음성이 입력되었을 때 동일한 음성길이를 가진 아주 많이 오른쪽으로 인식하는 경우가 있다. 이런 오류를 해결하고자 각 패턴의 DTW 오차 값 범위와 표준 패턴의 음성길이를 기준으로 임계값을 퍼지 추론하여 명령으로서 수락 여부를 결정하였다. 판단이 애매한 부분은 사용자에게 질의를 하여 응답에 따라 수락 여부를 결정하였다.

Index of performance is dervied from consideration of movement times in routine selection tasks. The discrete movement task employed in this study consisted of moving a cursor from the home position to targets located 6.8, 15.9, 25.0, and 34.0 cm. The target widths were 2.3, 4.5, and 6.8cm. Eight subjects with nomovement disabilities took part in the experiment. Fitts' law is found to be applicable in this experiment.

컴퓨터의 급속한 발전 속도와 맞물려 사용자의 위지나 몸짓, 감성을 인지하는 보다 편리하고 자연스러운 휴먼 인터페이스에 대한 요구가 늘어나고 있다. 휴면 인터페이스 가운데 응시 위치 추적은 현재 사용자가 쳐다보고 있는 위치를 컴퓨터 시각 인식 방법을 통하여 파악하는 연구이다. 본 논문에서는 여러 감성 컴퓨터 인터페이스 중 눈동자를 통해 컴퓨터의 입력장치를 간접적으로 제어하는 방법에 대해 기술한다. 웹 카메라를 통해 입력 받은 영상을 이용하여 눈동자의 위치 이동을 탐색하여 마우스를 제어한다.

최근 소프트웨어 개발에서의 핵심어인 객체지향(object oriented)은 1970년대 초부터 중요하게 인식 되기 시작했다. 현재는 객체지향에 대한 많은 관련 연구를 통하여 그 활용범위가 증대되고 있다. 본 연구에서는 객체지향 연구의 한 부분인 디자인 패턴 중에서 많이 이용되는 Iterator(Cursor) Pattern을 활용하여 닷넷(.NET) 기반에서의 특정 비즈니스를 위한 데이터 접속 객체를 연구하였다.

인터넷 광고의 시장 및 기술은 매년 급속하게 성장 및 발전하고 있으며 우리 생활에서 캐놓을 수 없는 한 분야로써 자리잡고 있다. 이러한 인터넷 광고는 일반적으로 전달되는 TV나 라디오와 같은 방송매체의 광고와는 달리 인터넷상에서 사용자의 작업을 방해하지 않으면서도 효과적으로 사용자의 관심을 끌어 광고 내용을 전달하는 것이 중요하다. 왜냐하면 강제적으로 사용자에게 전달되는 광고는 사용자의 임의의 작업을 방해하여 심한 불쾌감을 줄 수 있으며, 너무 정적이어서 관심을 유도하지 못하는 광고는 그 효과가 매우 낮기 때문이다. 본 논문에서는 웹 상에서 사용자의 작업을 최대한 방해하지 않으면서 관심을 유도할 수 있는 인터넷 광고 기법을 제안하고 기존 광고와의 비교 실험을 통하여 제안된 기법의 효과를 검증하여 본다.

Objective: The aim of this study is to investigate visual feedback effects and human performance in the foot mouse control. Background: Generally, computer mouse tasks are controlled by visual feedback. In order to understand the characteristics of a foot mouse control, it is important to investigate the patterns of visual feedback involved in foot-mouse control tasks. Human performance of foot mouse control is also an important factor to understand the foot mouse control. Method: Three types of mouse control were determined to investigate visual feedback effects and human performance in the foot mouse control. Visual feedback effects in the foot mouse control were compared with those of a typical hand mouse. The cursor movement speed and mental workload were measured in the three types of tasks and two types of mouses. Results: Mouse control tasks with an element of homing-in to the target were more quickly performed by the hand mouse than the foot mouse. Mental workload was also higher in the foot mouse than the hand mouse. However, in the steering movement, human performance of the foot mouse control was not lower than that of the hand mouse control. Visual feedback in the foot mouse control was less required than in the hand mouse control. Conclusion: The foot mouse was not efficient in the most mouse control tasks, compared to the hand mouse. However, the foot mouse was efficient in the steering movement, moving a cursor within a path with lateral constraints. Application: The results of this study might help to develop the foot mouse.

In this paper, we propose new algorithm for positioning of mouse cursor using fingertip direction on kinect depth camera. The proposed algorithm uses center of parm points from distance transform when fingertip point toward screen. Otherwise, algorithm use fingertip points. After image preprocessing, the center of parm points is calculated from distance transform results. If the direction of the finger towards the camera becomes close to the distance between the fingertip point and center of parm point, it is possible to improve the accuracy of positioning by using the center of parm point. After remove arm on image, the fingertip points is obtained by using a pixel on the long distance from the center of the image. To calculate accuracy of mouse positioning, we selected any 5 points. Also, we calculated error rate between reference points and mouse points by performed 500 times. The error rate results could be confirmed the accuracy of our algorithm indicated an average error rate of less than 11%.

This paper is a matter of remote control apparatus and display remote control system comprising the same. The remote controller is a wireless remote pointing device that is included a function of mouse and a function of remote controller for VOD etc. It is assembled a sending signal part to communicate with display device, a image sensor part to capture a scene of front view and a main body. Also, it includes a control part that analyzes the captured image, calculates a relative moving factor that main body is moved by user, and then controls the mouse cursor on the display device. The remote control apparatus is able to capture a seen of front view, to analyze the captured image, and to move a mouse cursor point on the display device as much as it calculated relative moving factor. Therefor it brings don the cost of production by a product desist that is increased user satisfaction. And it, using the patent and the new product desist, will make an epoch in development of the remote control system for Ubiquitous broadcasting industry.
